Fluorite with Pyrite and Geocronite-Jordanite
Excellent Atacocha Fluorite composed of octahedral crystals with cube modifications. The crystals are transparent to translucent with a very nice green color and are accompanied by bright small crystals of Pyrite and spherical aggregates of Jordanite-Geocronite crystals with curved and complex faces. The analyzes of the Sulphides of these new specimens from the Milpo mine (SEM-EDS and XRD) show a correlation between Geocronite-Jordanite, both are isostructural and forming series. Samples analyzed show that the composition moves in the intermediate zone of the series. Therefore, the correct thing would be to label these specimens as Geocronite-Jordanite. The condition of this specimen is excellent, without any noticeable damage.
